This application relates to improvements 1 'in fire extinguishingattachments for oil wells.

' Itis the vide an extremely simple and 'inexpenslve attachment for oilwell casings, which will effectively extinguish the dame, in case theoutrushing gas' and oil should catch fire, provision being made wherebytwo flat blankets 4or jets of `live steam may be forci- 'bly projectedvacross the passage through which the well is shooting, it having beenproven by experience that this method of extinguishing -is exceptionallyeiicient, jas oil wells throwing a stream of flame approximately twohundred fetin the air, have been succefully extinguished by theinvention, with-ease. y

ith the foregoing in view, the invention resides in the novel subjectmatterhereinafterdescribed and claimed; the description beingsupplemented by the accompanying S drawing.

Figure 1 1s a vertical sectional v view showing one form of myinvention.

Figure 2 is a sectional view at right anlgles to Fig. 1, as indicated byline 2-2 thereof. f Figure 3 is a horizontal `section on. line 3'-3 ofFig. 1.

Fi e 4 is a longitudinal sectional view showlng a slightly dierent formof construction. a o a Figure 5 is a side elevation.

In the drawings above briefly described, the numeral 1 desigates -avertically elongated passagegmem ormed from a short length of pipmg, sucas well casing, the lower end of said (passage member being externallythreade as indicated at 2, whereby an-appropriate coupling 3- may beprovidedfor mounting said -l'ember u pon the upper end of a well casing4. The upper'endmf` the bodyj member 1 is i alsopreferably threaded` asindicated at 5, so that4 a casing head, pipe section or the like, may becoupled thereto.'

Between its ends, the passage member 1 is venlarged by welding, brazingor otherwise securing a hollow 'collar 6 around the same, said collarhaving steam inlet means which referably consists of a pair ofdiametrica ly opposite ports 7 into which live steam supply pipes 8 maybe threaded.

object of the invention to pro-i -as indicated in r which is pre'ferablThe e member 1 is formed with a- 55 pair o vertically s aced steam inletports 9,' inthe form of sits formed through the wall of said memberbetween the interior of the latter and the interior of the hollowenlargement or collar 6. The upper port 9 extends substantiallythroughout half the circumference of the passage member l and is at theside of the, device adjacent one of the steam inlets 7 Similarly, theother port 9 occupies a proximately the'other circum- .ferentlal ha f ofthe passage member and is disposedadjacent the other' steam inlet; Theopposed walls of the slits or ports 9 may either be dis osed inhorizontal planes ig. 4, or' they may be slightly inclined as disclosedin Figs. 1 and 2. It will be seen that as soon as l1ve steam ispermittedto pass through the pipes 8, it wi l entirely fill the hollowcollar'6, around the passage member' 1 vand the steam from this spacewill be forcibly directed across the passage member, in verticallyspaced planes, by means of 'the ports 9, forming flat jets or blanketsof steam which co-operate in eifectively chocking down the dis- 1 chargefrom the well and extinguishing the flame. .f

While inl the present ap lication, I have disclosed only one form o?construction, it is to be understood-that within the scope of theinvention `as claimed, numerous modiications may be made.

I claim: ,o 1

1. A11l o'il well fire extinguisher -comprising a passage havin a slotin its side for directing a flatbla et of steam across the passage, theside walls of said slot being disposed on 'lines oblique tothe passageaxis to direct ,thel steam obliquely across said passage, and a steaminlet for supplying steam to said slot.

2. An oil well re extingulsher comprising apassage and means associatedwith said passage for directing one flat blanket of steam obliquelyupward across the passage and for dlrecting another fiat blanket ofsteam obliquely downward across said passage.

3. A fire( extinguisher comprising a vertically disposed passagev memberhaving a i circumferentially extendin chamber and upper and lower steamin et slots opening from said chamber into the interior of the lpassage, one of said slots extendin substantially throughout half thecircum erence of the passage while the other slot extends'substantiallythroughout the remainder of such circumference, and means for supplyingsteam to said chamber.

4. A fire extinguisher comprising a body having means for connecting itto a well casing, said body being provided with a passage forcommunication with the casing, with a chamber around the passage, and

with slots from said chamber into said passage, said slots beingdisposed in a plurality of spaced transverse planes and occupyingdifferent segmental portions of the circumference of the passage,andmeans for admitting a .non-combustible fluid to said chamber fordischarge into the passage through said slots.. v

5. A structure as specified in 'claim 7; said slots jointlyextending-substantially throughout the circumference of thepassage.`

6. A fire extinguisher comprising a vertically elongated passa e member`having means at its llower end or coupling it to an oil well casing,said passage member having a hollow enlargement which circumferentiallysurrounds said member and provides therewith an annular chamber, saidchamber being provided with steam inlet means said passage member havingan upper and a, ower port leading from said chamber to the interior ofsaid passage member, one of said ports occupying substantially half thecircumference of said vpassage member while the other port occupiessubstantially the remainder of such circumference.

In testimony whereof I have hereunto aixed my signature.

EDWARD ALBERT KLIEWER.
